which will run all the tests against the configured DEV environment in your madcow-config.xml.

Then you have to simply point your CI build tool to look for junit style test results in the /results/junit-report/ folder and you will get beautiful test result build server integration.
Probably a good idea to get that whole results directory archived with each build too, to ensure you keep copies of the details madcow results as well!

I want to see the source code and get involved and contribute!

Great because Madcow 2.0 is fully open source under the Apache 2.0 License!
